WATER-COOLER.

To all whom it may concern:

I Be it known that I, GEORGE P. Pn'rnoro- LAB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Water-Coolers, (Case 1,) of which the following is afull, clear, concise, and exact description, referencelbeing hadto the accompanying drawings, forming a part of this specification.

My invention relates to water coolers, its object being to provide improved construction and control therefor.

The water cooler of "y inventionis adapted for connection witha source of water supply, for instance with a faucet, provision bemg made to automatically shut off the flow of water to-the cooler tank when the tank becomes filled. An ice chamber is inserted in the tank about which the water passes to be cooled. When water is Withdrawn the'automatic controlliiig meansisfactuated to allow the tank to be refilled, and when refilled the automatic means again shuts off the flow of I Specification of Letters Patent.

mechanism whereby it may connect with a faucet or directly with the Water pipes from which the tank is to'be fed. The body of the filter is of greater diainetdi and composed of the two parts 7 and 8 having threaded connection at 9 with each other, as shown, these parts being reduced to form the ends 3 and 5 already nientioned fln the front end ,of the part 7 straining material, such as wire gauze, this disk being convex toward the entrance side of the filter and preferably held statio'narily in placel Near the rear end ofthe part? is a similar disk 10 in which the openings may be of any size, preferably a little larger than those in the disk 9, this second disk being also convex toward the entrance end of the filter. This disk is preferablyremovaole and tofforrn 'a seat thereiorthawallsfoi the part maybe indented. at several places, or may have the complete annular ndentation ii to form the annular ledge 12.- Concentric with this disklO and secured thereto at its center is the disk or fender .13 which, how

water to the tank. A filter mechanism also forms part of the tank through which the water must pass before reaching the tank, being thereby filtered from all. dirt and imurities. A drip or overflow pan forms the ase of the cooler, being connected with the ice chest, and has an'overfiow which normally takes care of surplus water from the ice chamber and has also a faucet whereby it may be drained quickly. In the accompanying drawing I have shown the arrangement and the various parts of the cooler. v I Figure 1 is an elevation view showi v the complete cooler; Fig.2 is a to view wit the cover removed; Fig.3 is a iametrical sectional view taken on line 3+3 of Fig. 2; and Fig. 4 is an enlarged sectional view of the fil ter. I

The main tank 1 l construction of may be cylindrical or of any other shape and hasacover 2 'wliich ma be of any design. Extending iritothe tan near the top thereof is the end 3 of a filter 4 which end may be threaded into the tank wall as shown. The other end 5 of the filter is threaded for connection with piping 6 0r ever, is concave toward the entrance end of the filter. Thisidisk is of smaller diameter than the part 7 to leave the annular space 14 between its edges and the walls of the part 7, this disk being also solid. The disk 10 may be given sulficient spring so that when slid into the-part 7 againsttheridge 12 it will maintain itself withv the diskl3 in position. The object of the fender 13 is toprctect the disk 10 against the impact of the water entering through the end 5,. the im act oi the water being taken up by the dis and after having to a cat degree lost its energy, is slowly forced over the edges of the disk and througlthe screen diskiO, being then forced through straining medium 15 and then upwardly though the fine meshed disk 9 toward the, tank; this straining medium 15 may be charco "l, sand or any other suit able substance. stances strained from thewater by the disk 10 willdrop to thebottom and into the opening 16 which connects through .iping 17 with aiaucet or cook 18 which may e readily secured to the side of the tank as shown. The entrance of water from the filter into the Impurities and Eo'reign suhtank is controlled by the cock 19 which in turn is controlled by the hollow ball 20 connected therewith by the arm 21, the adjust ment being such that when the tank is full the ball will be raised by the water to its uppermost position to close the valve or cook 19, and when water is taken from the tank the ball will follow the water and will open the valve 19, whereupon water will flow from the filter until the tank is again filled and the valve closed when the ball again reaches its uppermost position. Water may be drawn from the tank through the faucet or other similar mechanism 22 communicating with the lower end of the tank.

To suitably cool the water in the tank I provide the ice box or chamber 23 which'may be square, cylindrical, or other desired sha e, but which preferably extends diagonally through the tank as shown, its upper end 24 being open and a door 25 being provided therefor, which door may be hinged to" the tank. The section of this ice box is such .that the water may be freely passed thereabout, also that it may contain suflicent ice to suitably cool the water. Surrounding the lower end of the water tank is a drip pan 26 which has a larger diameter than the tank and secured theretoto be concentric therewith and to leave a space between its bottom and the lower end of the tank, as shown.

This pan may be secured in any manner to the tank, being here shown as secured thereto along its upper edge 27, which is curved inwardly to meet the "tank. Extending from the lower end of the ice box and into the drip pan is an opening or pipe 28 whereby the surface Water from the melting ice maydrain into the drip pan. Extending from any suitable point at the bottom of the drip pan .is

a faucet 29 by means of which the pan may be quickly drained. However, the water from the faucet 29 from a point between the,

valve 31 in said faucet and the drip pan, and the upper end 32 of this drip pipe is bent over, as shown, with the top just a short distance below the up or end of the drip pan forming.

thus a sort o si hon arrangement, and there Will be no out! ow from this pipe untilthe.

drip pan has been filled and the water raised,

in the drip pipe over the pan, whereafter the drip pipe will be drained to a level of the outlot and of the drip wipe. I ing directly from t 10 tank passes through the from the faucets and drip pipe.

The faucet 22 comwall of the drip pan and suitable bushing may beprovided to prevent leakage.

The tank may be secured in any convenient position and may be supported on a shelf .or in any other manner. The faucets 22 and 29 and the drip pipe 30 are preferably close together and an auxiliary drip pan (not shown) may be supported therein, or the entire cooler may be placed in position over a sink, which wouldthen catch all the overflow By means of the automatic mechanism the tank is always filled immediately after withdrawal of water therefrom and the water in the tank is constantly being cooled. By means of the filter only clean. water can enter the tank. As the tank is always filled, water can be withdrawn at any time from the faucet 18, but the main purpose of this faucet connection is to clean the filter and remove therefrom the sediment or foreign substances filtered from the'water, the force of the water entering theend 5 being sufficient to remove all sediment or foreign substances from the screen 10 and to flush out said substances and sediment through the pipe 17 and the faucet 18. The filter can be furthercleaned by unscrewing the cap or part 8.

In addition to using my invention as a water cooler, I find it convenient to supply means whereby milk, cream or other liquids may be easily and quickly cooled. For this purpose I place a secondarytank 33 within the main tank 1 and adjacent to the ice chest 23, the topof the secondary tank being open so that the liquids can be poured therein. A

faucet 34 passes through the walls of the main tank and the drip pan and connects to the bottom portion of the secondary tank 33, this faucet being for the purpose of withdrawing the liquids as required.
